What database are you using? If you're using SQL Server, you can do
something like this by using the 'UNION' keyword:

<warning: Vaporcode>

Private Sub cmdKeyWordSearch_Click()
Dim strKeyWord As String
Dim strSQL As String
Dim SplitKeyWord() As String
Dim x As Integer

strKeyWord = " " + txtKeyWord.Text
SplitKeyWord = Split(strKeyWord)

For x = LBound(SplitKeyWord) To UBound(SplitKeyWord)
strSQL = strSQL & "SELECT * FROM ClientAddresses " & _
"WHERE Company LIKE '%" & SplitKeyWord(x) & "%'"
If x < UBound(SplitKeyWord) Then
strSQL = strSQL & " UNION "
End If
Next x
adoClients.RecordSource = strSQL
adoClients.Refresh
dgrdClients.Visible = True
End Sub

What this should do is produce a SQL statement like this:

SELECT * FROM ClientAddresses WHERE Company LIKE '%foobar%'
UNION
SELECT * FROM ClientAddresses WHERE Company LIKE '%barfoo%'
UNION
SELECT * FROM ClientAddresses...etc

However, a more efficient way to do this might be to append OR statements
onto your SQL, so the command ends up looking like:

SELECT * FROM ClientAddresses
WHERE Company LIKE '%foobar%'
OR Company LIKE '%barfoo%'
OR Company LIKE...etc
